[Clinical Experience of Beating Heart Atrial Septostomy Using a Device for Coronary Artery Anastomosis Site Creator].

ABSTRACT

BACKGROUND: Intra-atrial communication was mandatory for several congenital cardiac diseases, such as pulmonary atresia with intact ventricular septum (PA/IVS), and either sided aortoventricular valve atresia. We assessed whether the new methods of atrial septal defect(ASD)creation was effective. METHODS: We experienced 4 cases of the surgical atrial septostomy performed under on-pump beating. We used a new device, a circular punch out defect creator. RESULTS: All cases were alive. The mean ASD diameter was enlarged from 4.37 mm to 5.55 mm and the mean ASD shunt flow was significantly decreased from 1.47 m/s to 1.11 m/s. CONCLUSIONS: We performed the surgical atrial septostomy using an aortic puncher under beating heart effectively and safely.
